Event Data
The SetInitialDashboardState event's data class is SetInitialDashboardStateWpfEventArgs. The following properties provide information specific to this event:

Remarks
This example demonstrates how to manage dashboard state to save and restore selected master filters values, current drill-down levels, and other parameters such as Treemap layers.
When the application starts, the DashboardControl loads the dashboard and the DashboardState object is deserialized and restored using the GetDataFromString method in the DashboardControl.SetInitialDashboardState event handler.

public static readonly string PropertyName = "DashboardState";
public MainWindow()
{
InitializeComponent();
}
DashboardState GetDataFromString(string customPropertyValue){
DashboardState dState = new DashboardState();
if(!string.IsNullOrEmpty(customPropertyValue)) {
var xmlStateEl = XDocument.Parse(customPropertyValue);
dState.LoadFromXml(xmlStateEl);
}
return dState;
}
private void dashboardControl_SetInitialDashboardState(object sender, DevExpress.DashboardWpf.SetInitialDashboardStateWpfEventArgs e){
var state = GetDataFromString(dashboardControl.Dashboard.CustomProperties.GetValue(PropertyName));
e.InitialState = state;
}
}
}
